| Abstract | On the farm level , different irrigation structures are us ed. Though the structures are relatively small, they perform a sig11ificant role to convey and control the irrigation water safely to the point of application, reducing the loss of irrigation water and preventing the soil erosion. Farm irrigation structures, namely drop structures , channel sections, Diversion hoxos, and irrigation outlets were designed and fabricated using ferrocement as an alternative material of construction. Hydraulic and structural testing of the structures were carried out to evaluate their performances. The cost analysis of the structures was also done and the ferrocement structures were compared with similar RCC structures. Results obtained indicate that the structures performed well both hydraulically and structurally. The channel section was able to Lak e a maximum patch load of 2100 kg. and no crack was observed at this load. The cost analysis indicate that the forrocement drop structure is more costly than the RCC drop structure. The cost of ferrocement channel section was found 37% higher than the similar RCC channel section . However , in the case of ferrocement channel section this extra cost can be compensated by the less transportation cost and the reduction in the number of joints between the channel sections. Using the ferrocement in addition to the RCC, the diversion box-panel/irrigation outlet could be fabricated with a smooth sealing finish around the orifice which enabled to reduce the leakage of water significantly. |
